Embodiment Construction

[0051] Reference will now be made in detail to various embodiments, one or more examples of which are illustrated in the various figures. Each example is provided by way of illustration and not intended as a limitation. For example, features illustrated or described as part of one embodiment can be used on or in conjunction with other embodiments to yield still further embodiments. It is intended that the present disclosure includes such modifications and variations.

[0052] figure 1 A wind turbine 100 is shown. The wind turbine 100 comprises a tower 110 on which a nacelle 120 is mounted. The nacelle 120 is rotatable about the vertical axis of the tower. A generator for converting rotational energy into electrical energy is arranged within the nacelle 120 . The generator is connected to a hub 130, which is rotatable about a horizontal axis. Three rotor blades 140 are connected to hub 130 . Rotor blades 140 and hub 130 together form a wind rotor of wind turbine 100 . W...

Abstract

The present invention relates to a method for controlling a proximity sensor of a wind turbine. The present disclosure relates to a method for controlling at least one proximity sensor of a wind turbine, the wind turbine comprising a rotor shaft, the at least one proximity sensor being adapted to measure a radial displacement of the rotor shaft; the method includes: providing at least one reference value, detecting an output of the at least one proximity sensor, the output depending on a measured distance by the respective proximity sensor; comparing the detected output of the proximity sensor with at least one reference value. Further, the present relates to a control arrangement for a wind turbine, the wind turbine comprising a wind rotor shaft; wherein the control arrangement comprises at least one proximity sensor being adapted to measure a radial displacement of the rotor shaft, wherein the at least one proximity sensor is adapted to generate an output signal depending on a measured distance by the respective proximity sensor; wherein the control arrangement further comprises a control device, the control device being adapted to receive the output signal of the at least one proximity sensor, wherein the control device is adapted to compare the output signal with at least one reference value.

Description

technical field [0001] The present disclosure relates to a method for controlling at least one proximity sensor of a wind turbine comprising a rotor shaft. Additionally, the present disclosure relates to control devices. More specifically, the present disclosure relates to a control device for a wind turbine comprising a wind rotor shaft. Additionally, the present disclosure relates to wind turbines. More particularly it relates to a wind turbine comprising a control arrangement, wherein the control arrangement comprises at least one proximity sensor adapted to measure a radial displacement of the rotor shaft. Background technique [0002] The wind rotor blades are attached to the hub, which is attached to the wind rotor shaft. Typically, the wind rotor shaft is bent in a radial direction of the wind rotor shaft depending on the wind. In some wind turbines, asymmetric load control is provided in order to control and reduce the loads on the wind turbine. For that reason,...
